well, i sell new locks with keys, but you might be able to take yours to gm to have it rekeyed. i tried several locksmiths and could not get anyone to figure out how to rekey those power lock cylinders. but they told me gm should be able to do it. if that is all that is wrong with it try that maybe or let me know. i also have the gasket that goes under it and a new polished stainless steel bezel to replace the pitted chrome one. i have not compleeted the motor swap i started. i have been told that the 80 blazer motors work , but i bought one and it is not even close, i was going to pull the casing all apart and try swapping just the interanal motor parts to see if that works, but i got too busy with a million other things.
